The argument that players should be less war-shy and liberate conquered city-states is completely facile
No, if you want to play as a peacenik then come up with strategies and
tactics yourself. Don't expect the base game to be nerfed to suit your
(minority) preference. Or use mods that suit your style.
It's completely illogical for (most) AI players to conquer city-states and remove any bonuses they provide, especially when they get so many settlers and other leg-ups in the early game.
It's not a bad tactic if they remove CS that could provide bonuses to other
civs or human players.
Obviously some AI should be very aggressive, no problem with that (I'm a war-monger by temperament), but in just about every game the city-states are getting decimated - the devs might as well remove them altogether as things stand.
Remove all city-states in the base game because they don't fit
your preferred way of playing? Use a mod to play as Pingu, but
don't ruin the way the majority like to play.
